In 2011, Wenbing officially decided to carry out a great research that has never been done before or since—the technology of time rewinding.

Based on his abundant theoretical knowledge, Wen Bing formulated basic research ideas. First of all, he used his knowledge base of medical research to develop a potion that can make the human mind in a highly active and divergent state, and lay the foundation for accepting future memories. The second is to find a specific way to accept future memories.

Wen Bing used his financial reserves over the years to open his own laboratory, and at the same time recruited several experts in related fields, and won the trust of many people with high-sounding statements such as "using time technology for the benefit of human development".

But in the beginning, Wen Bing did not focus his work on developing potions. Wen Bing naturally understands that it is far easier for machines to realize the active thinking than to develop potions suitable for the human body. If we create a machine that can accept information about the future, and then let the machine successfully bring future research back to the present, then the duration of research can be shortened from a few years to several decades to a fixed time, which is the time required to develop a machine.

With the artificial intelligence research results in Yuyun's hands as the foundation, the process of Wen Bing's creation of Yongqi can be described as smooth. However, he was afraid that Yongqi, who had the ability to time, would lose control, so he did not give Yongqi the ability to walk. Yongqi's ability is limited to receiving and transmitting information.

In 2013, after the successful development of artificial intelligence Yongqi, Wenbing also endowed it with speakers, earpieces, cameras, cameras, and arms that can be written and simulated, so that Yongqi can accept the input and output of information such as images and sounds in addition to text.

When Wen Bing eagerly asked Yongqi if he knew the success of his future research, he received a negative answer. Wen Bing understood that he couldn't rush it, and the specific method of time rewind had not yet been found, and it was normal that he couldn't get an answer from Yongqi's mouth.

In addition, based on deep thinking about the soul and memory, Wen Bing came to a conclusion: it may have to be something that happened in order to go back in time with the memory. Among them, the process of thinking, Yuyun has also stated to alkanes. But at this stage, the civilian army is not 100% certain. In the past two years, some of the research led by colleagues was still in the cognitive stage of "drinking the potion and immediately knowing the future".

Based on the new cognitive conclusions, Wen Bing believes that if his experimental ideas are not wrong, he already has artificial intelligence that can transmit future information. If your own experimental ideas don't work, then even if Yuyun goes against you, it's pointless. Therefore, after completing the creation of Yongqi, Wen Bing found Yuyun and told him about his future experimental plans and ideas. Of course, it is based on the inference that things must happen in order to go back in time, including human centipede experiments and so on. Wen Bing hopes that Yuyun can understand his ambition and join him in his research. Not surprisingly, the two eventually broke up.

At this time, Wenbing had already planned most of the things in the future. In fact, as Wen Bing speculated, things must happen before they can go back in time, but they have not found a way to achieve it. Therefore, many things in the future are actually carried out in an orderly manner according to the original plan of the civilian soldiers.

Fast forward to the end of 2018. Wen Bing had a strong premonition that his research was about to succeed. He needs to find a candidate who meets the following criteria. First, you must have a high level of intelligence and be able to trust and entrust him to complete his experiments. Second, they must have a greater weakness and can be threatened by themselves. Third, the age should not be too old, which will be more conducive to your complete control over the candidate. And another advantage of being young is that the physical condition is generally better, and it is not easy to suffer from diseases that are intolerant to the potion. Fourth, it can't be artificial intelligence. Until humans get the earliest time rewind node, an AI with the ability to go back in time cannot be given the ability to walk, otherwise everything will become uncontrollable.

Based on these four guidelines, Wen Bing met Brother Shui through a friend who was a teacher in high school. What happened to Brother Shui later, alkanes have already heard from him.

Back to the story line of Wen Bing, one day in September 2020, Yongqi, who was hidden in the corner by Wen Bing, suddenly spoke. He told the soldiers that the future soldiers had accomplished a lot. First of all, Wen Bing found a way to go back in time, and verified the feasibility on Yongqi. Secondly, the time backtracking experiment has also been verified on Brother Shui. A potion for humans was successfully developed, and the specific recipe for the potion was brought back by Eternal Rider. In the end, the future Wenbing found a way to let Yongqi enter the university that Brother Shui was admitted to as an ordinary student.

The civilian soldiers can start to show their skills.

Wen Bing wrote all the experiments he needed to complete into a book of "Experimental Rules". In the next time, he found Brother Shui, explained to him all the theoretical knowledge related to time rewinding, and on October 13, 2020, persuaded Brother Shui to cooperate with the experiment and drink the potion. Of course, before Brother Shui drank the potion, Wen Bing kidnapped his best friend Oyster. After Brother Shui discovered that what Wen Bing wanted to do by himself was a lot of cruel human experiments, he tried to resist through hundreds of time backtracks, but all of them failed.

After Brother Shui drank the potion, Wen Bing fitted Yongqi with a prosthetic leg, giving Yongqi the ability to walk, and made him disguise himself as a human and become a classmate in Brother Shui's class. Wen Bing also repeatedly emphasized that swearing more can make him act more like a student, which is why Yongqi speaks informally. But Wen Bing didn't let Brother Shui know Yongqi's true identity. Yongqi can use time to go back to spy on Brother Shui's experiments, and Brother Shui can go back in time to when Yongqi can't walk. Wen Bing needs artificial intelligence to know whether Brother Shui cooperates with the experiment, but he hopes that humans can absolutely control artificial intelligence.

After Brother Shui completes all the experiments and goes back to the earliest point in time to tell Wen Bing, Wen Bing will tell everything to Yongqi, who has no ability to move, and let Yongqi go back to 2013 and tell Wen Bing with everything, including the potion formula and the conclusions of various experiments. If Wen Bing's body does not have the problem of potion intolerance, and at the same time he has a complete knowledge of the time retrospective theoretical system, Wen Bing at that time can completely close the artificial intelligence of Yongqi, dissolve the laboratory, drink the potion, and start his own life.

In fact, Wen Bing can split the experiment and let Yongqi go back in time again and again, so that Brother Shui only has the memory of agreeing to Wen Bing to do a certain experiment every time, so that Brother Shui's acceptance will be much higher. But there is a reason why they don't.

First of all, there is a correlation between many experiments. Brother Shui needs to rely on a lot of experimental experience to improve the efficiency and rigor of his experiments.

Secondly, Brother Shui can't be allowed to know the identity of Yongqi. Once discovered by Brother Shui, Wen Bing judged whether he had the means to cooperate with the experiment, relying on the artificial intelligence of Yongqi, as long as Brother Shui directly killed Yongqi, so that Yongqi could not go back in time to transmit information, and then go back to the earliest timeline to kill Yongqi, who was still unclear about his defeat, Wen Bing would no longer have a way to verify the authenticity of all the experimental conclusions that Brother Shui said. Therefore, the act of Yongqi snooping experiments is risky. If each experiment is done separately, then every experiment needs to be snooped. The more you snoop and the more you use your ability to backtrack, the more likely you are to leave a trail. For example, Yongqi told Alkane Yuyun that the reason for the name change may be caused by the program's incorrect combing of the timeline.

Therefore, the optimal approach is to set an experiment that breaks the lower limit of human nature, and only need to spy on whether this experiment has been done in earnest, and then you can infer whether other experiments that are more acceptable have been completed. Once it is found that Brother Shui has really done this experiment, Yongqi will ignore all the experiments that have been completed before, go back in time to a little bit after Brother Shui drank the potion, make sure that he will not erase the memory of Brother Shui's fruitless resistance, and then send a radio message to Yuyun's mobile phone. Of course, Yongqi and Wen Bing do not have the memory of Brother Shui's many resistances, but all this is expected by Wen Bing. Therefore, when Wen Bing told Brother Shui about his experimental process vividly, as long as the mobile phone did not receive the message, he thought that Brother Shui was lying. Since this behavior will erase the results of Brother Shui's previous experiments, Wen Bing will only ask Yongqi to spy on an experiment that he deliberately set to break through the lower limit, and tell him about the time back. In this way, while ensuring that only one experiment is snooped on and the risk of Yongqi's exposure is minimized, Shui Ge's experimental conclusions are highly credible.

Of course, Wen Bing will not completely believe in Brother Shui's experimental conclusions just through this experiment. Based on Wen Bing's rich medical knowledge, the conclusions of many experiments Wen Bing had an approximate result in mind.

In order to ensure that Yongqi could know the specific time when Brother Shui would conduct this experiment that broke through the lower limit, Wen Bing told Brother Shui that he had to do the next experiment every few days, and record the time of each experiment in his notebook. If he only uses one point in time to go back and do different experiments, or doesn't keep a notebook of what experiments he plans to do every few days, he will soon have a messy timeline and can't remember what he has done. However, this is not sensational, even if Wen Bing did not say this to Brother Shui, it is very likely that Brother Shui will use such an experimental method to avoid confusion in the timeline. Therefore, with the help of the "Experiment Manual", Yongqi, who has the ability to time, can naturally easily know the experimental time of Brother Shui.

And the one mentioned by Wen Bing, the experiment that broke through the lower limit of human nature, was the human centipede experiment.
